聚丙烯用附着力促进剂研究进展

从氯化聚丙烯（CPP）的改性、附着力促进剂的无氯化和水性化三个方面综述了聚丙烯（PP）用附着力促进剂的研究进展。介绍了不饱和酸（酐）改性CPP的研究和无氯附着力促进剂的制备方法，阐述了机械法、相反转法、自乳化法和乳液聚合法制备水性附着力促进剂时各自的优缺点和适用范围，总结了可控自由基聚合在PP用附着力促进剂领域的应用。最后指出在进一步的研究中还需要提高无氯附着力促进剂与面漆树脂相容性和水性附着力促进剂的稳定性。

Research progress of polypropylene adhesion promoter

The recent development of polypropylene adhesion promoter is reviewed,including modification of chlorinated polypropylene,chlorine-free adhesion promoter and waterborne adhesion promoter.The modification of chlorinated polypropylene with unsaturated anhydride and the preparation of chlorine-free adhesion promoter are introduced.Mechanical method,phase inversion technique,spontaneous emulsification method and emulsion polymerization technique are used to prepare waterborne adhesion promoter,and the characteristics of each methods are presented.The application of controlled radical polymerization is also summarized.The compatibility between topcoat and chlorine-free adhesion promoter and the stability of waterborne adhesion promoter should be improved in further study.
